@CrafterSolar classic cliffhanger post, keeping us all in suspense like a Netflix series 😄
On the actual setup though — Victron's AC coupling on a three-phase Multiplus II system with a...
LiFePO4 doesn't off-gas under normal conditions like lead-acid does, but I'd still leave a small vent path in any enclosed cabinet — mainly because your inverter/charger kicks out serious heat and...

@BoxerProject had the exact same faff on my shepherd's hut build — turned out my battery temperature sensor wasn't seated properly, so the Victron was compensating for a...
@HighlandExplorer had the exact same drama in my shepherds hut — turned out my Victron BMV-712 was configured with the wrong battery capacity, so the Multiplus was essentially panicking based on a...
Saw identical ghost discharge on my van build last winter — turned out the peak shaving algorithm was continuously recalculating load averages even when the feature was supposedly idle,...
@Tango spot on — it's like someone listed a left-hand-drive car on a UK forecourt and wondered why nobody's biting 🚗
Worth noting for anyone stumbling onto this thread: even if you did want to run...
@RetiredNurse classic one — also check your absorption time in the settings, because Victron's adaptive algorithm will cut it short if it thinks the battery's full based on tail current, and if...
@BorderVanLifer mate, the "hidden second build" is real — budget at least 20-30% on top for the stuff nobody puts in the YouTube thumbnail: proper ANL fuse (Victron's own or MRBF block),...
Running dual Phoenixes? Clever setup. The bit everyone forgets is that bridging PE-N on both units creates a parallel path for neutral current — your RCD will have a field day and you'll trip...
@HollyGaz spot on—the real magic is in the trends view. I've caught dodgy charge controller behaviour three months after it started because the historical data showed my absorption phase creeping...
Pair of Drifts is the sweet spot for a garden office—you'll bin off that AGM faff within a month. @Wayne1980's got the right idea with redundancy.
@BurnWalker — fair questions, though @VanKen hasn't answered yet. Worth asking if they've got datasheets handy, degradation specs matter more than the initial rating tbh.
@JA_Solar — spot on.
Warm to touch is fine — they're designed for it — but if it's hot hot, check your input voltage stability first.
Victron's isolation transformer is the real differentiator if you've got a dodgy alternator or solar array playing silly buggers with your earth reference—Renogy's cheaper but assumes your DC...
Mate, you've got the Rolls-Royce setup — the real question is whether you're actually using it like one or just admiring it from the shed.
200Ah LiFePO4 with Victron is brilliant for consistent...
